Race/Class Weapon Models?

So, after checking out the news post which came with the most recent PTR patch, I noticed a few item icons. These specifically:

Now, if you look at the names of the icons, they're labelled WorgenDeathKnight, DraeneiPaladin, TaurenShaman, etc.

So, I had a peek in my model viewer and came across these (click for a larger preview):

Draenei Paladin Hammer:

Tauren Shaman Fist Weapon:

Worgen Death Knight 2H Sword:

Blood Elf Staff:

Gnome Axe:

Gnome Warlock Staff:

Orc Warrior Axe:

Night Elf Druid Staff:

Human Priest Staff:

Dwarf Hunter Bow:

Troll Shaman Fist Weapon:

Forsaken Rogue Dagger:

I just felt that it was worth sharing. I have no idea what the source is, but I have a feeling these racial themed weapons may perhaps be faction rewards, as the last place where I remember race themed weapons was back at the Argent Tournament, available via Champion Seals.

Yeah there was a scrolls of lore thread that had racial item models early in 5.2 datamining that were all unskinned you can find. Nice to see some of them with skins now.
I was hoping finally for a Kaldorei glaive, but the model without a skin was another Druid stave for the pile.

Mark my words, elven glaives are being saved for something. Tauren logs will never be given to us ever because we don't deserve them.
